To @ZZ whom, t may con/cern,.-

Be it known that I, ROBERT R. LAWSON, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements 4in 'Envelop- Fasteners, of which the following is a specilication.

My invention relates to a new and useful improvement in envelop fasteners or clips to secure the flap of an envelop more firmly to the body of the same.

It refers more especially to that type ofv envelop which it is desired to'fasten securely, but not to seal, so that the envelop may be opened and closed again without injury to it or to the fastening, and it is similar in action to those envelope which are closed and fastened by a device having metal prongs adapted to project through an opening in the iiap andto be bent 'over and against the body of the same to fasten it when closed. The difculty which has heretofore existed with devices of this character is that such fastenings are put through the body of the envelop in such a manner that when pressure or strain is brought to bear against it by reason of the fact that the envelop is lilled with goods or otherwise there is not resistance enough or strength enough to keep it from breaking loose or tearing away from the envelop or package, orif it Works loose and the package is torn open in consequence it permits the contents to be lost in transit, or because itis loosely attached to the envelop which it fastens it works backward and forward and its metal base has a tendency to scratch the goods against which it presses and with which the envelop may be filled. A further diculty has resulted .from the tendency of such devices to slip or move about in the act of bending the prongs thereof to fasten the flap in place.l

The present device is designed to overcome such disadvantages and to provide a small and effective envelop fastening or' clip in whichk strength is combined with convenience and economy.

I take a stout paper base which is cut in y the form of a disk, which paper may be reinforced with cloth for strength, the upper surface of which is gummed. Upon this paper disk I set the base of a brass clip similar to the well-known lMcGrill fastener, which consists of a piece of light brass or metal bent in the form of a T, the stem of which may be bent down on either side over the base.

Through the stem or prongs of this brass member I push a'smaller diskin form as is shown in Figure 2 of the drawings, which second disk has a hole in the center to admit the passage of the stem of the brass member through it. 'Ihe upper plane of this second paper disk is also gumrned. When. the brass member is placed upon the circular paper disk, the' second disk that goes over it is moistened' slightly and adheres to the gummed surface below, and this holds the head of the brass member firmly, making a fastener for use as I have indicated.

The envelop is made, preferably,with its flap doubled and gummed together in order to increase its strength, and the hole which receives the stern of the clip is cut through it, and a hole in the upper body of the envelop is also made to correspond with that in the flap when the same is bent over the body. The fastener ,is used by moistening the upper surface of its base .and then pressing it from the inside through the hole in the upper body of the envelop,'to which body it 'firmly adheres, with its prongs projecting and ready to be pushed through the hole in the flap of the envelop and the prongs bent over inthe ordinary manner, fastening it.

. My invention is clearly illustrated in the accompanying drawings.

Fig. l is a top plan view of the complete device detached from the envelop or receptacle. Fig. 2 is a cross-sectional viewtaken through the center of Fig. 1. Fig. 3 Vis a paper disk or base. Fig. 4 is a smaller disk or base of slightly-different form with a hole through the center. Fig. 5 is a section of an envelop, showing in outline the device attached to its body. Fig. 6 is a viewofa section of the envelop with the flap closed and held by the brass members of the device.

In operation the base ofthe 'If-shaped metal member is placed upon the paper disk or base, (indicated by Fig. 3,) one surface, called the upper surface, being covered with adhesive gum. A second base is indicated by Fig. 4, slightly smaller than the first base, through the center of which is a hole C, and the stem of the brass member is passed through the hole C of the smaller disk, which smaller disk is made to adhere to the larger disk by means of the adhesive gum thereon, clasping the head of the T-shaped brass member between the two, and forming thereby a substantial head. This device is then used to seal an envelop in the manner indicated by moistening the exposed surface of the gum on the larger paper disk not covered by the surface of the smaller disk, and the stem of the device is passed through a hole in the body of an envelop to be sealed from the inner side thereof, as shown in Fig. 5, and the hole e, as shown in the flap of the envelop in Fig. 5, is then brought down over the stem of the metal member which protrudes throughthe hole d, and the stem thus turned down to seal the envelop, as shown at e in Fig. 6.

Having thus described my invention, I claim- 1. An envelop-fastening device comprising a metallic member of a T shape, the stem of which consists of two prongs which may be bent laterally in an inverse direction, the head of said member being confined between two disks, the upper surface of said disks being covered with an adhesive gum, substantially as described and for the purposes mentioned.

2. An envelop-fastening device comprising a metal member of a T shape having for its stem duplicate prongs, each of said prongs being in excess substantially of one-half the length of the body member, base ,or head tween two paper disks, the upper surface of said disks being covered with adhesive gumthereof, the said base or head being placed be-
